Title: Transmission type screen
Inventor: MAEDA TERUNORI
IPC: G03B21/625
Filed: 1990-01-26
Abstract: PURPOSE:To reduce light reflection on the surface of the screen, to improve the contrast and resolution of a screen image, and to prevent an image like an out-of-focus image from being formed by forming a thin film of a fluororesin compound on the surface of a screen material. CONSTITUTION:The screen material 2a is an acrylic resin plate where a light diffusing material such as glass powder is mixed, and consequently, refracted light on a Fresnel lens surface 4 is diffused properly. Then the light is further diffused large to the right and left (horizontally) by a lenticular lens surface 5 provided on the front side and projected forward (toward an observer 3). In this case, the thin film 6 is formed of the fluororesin compound on at least one of the Fresnel lens surface 4 and lenticular surface 5. Consequently, the reflection rate of the projection light on the surface of the screen 2 can be decreased, the contrast and resolution of the screen image can be improved, and the image never become out-of-focus.

Title: Varnish coater for print
Inventor: ITOU KIYOSHI
IPC: B41F23/08
Filed: 1983-02-03
Abstract: PURPOSE:To prevent the hardening of varnish on a coating roller and to make uniform the thickness of a varnish film by a construction wherein one-way clutches with the coating roller on the driven side are provided between a blanket cylinder and the coating roller and between the coating roller and a driving source on the upstream side, respectively. CONSTITUTION:A coating roller 68 is driven to rotate by the either side of a motor 30 and a blanket cylinder 23 through the intermediary of one-way clutches 100 and 103. In this construction, the one-way clutch on the side of one driving element whose rotational speed is higher than the other transmits the rotation, while the one-way clutch on the side of the other driving element whose rotational speed is lower than the above runs idly. In other words, in the state in which the blanket cylinder is engaged, the coating roller 68 is driven by the blanket cylinder 23 through the intermediary of the one-way clutch 103, while the other clutch 100 runs idly. To the contrary, in the state in which the blanket cylinder is disengaged, the coating roller 68 is driven by the motor 30 through the intermediary of the one-way clutch 100, while the other clutch 103 runs idly. According to this construction, no irregularity of rotation occurs between the blanket cylinder and the coating roller. Therefore, the non-uniformity in the thickness of a varnish film is eliminated, and thus the print quality is improved.

IPC: H05B41/24
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce consumption power of a discharge lamp which can be lighted up efficiently and to reduce cost while a device is miniaturized by equalizing the bipolar value of a high-frequency current flowing through a plurality of discharge lamps by a simple circuit constitution. SOLUTION: An inverter circuit 10 transforms a voltage from a DC power source into a high-frequency voltage to transmit it to an oscillation transformer T. Low-pressure discharge lamps L1 and L2 are constituted by sealing a neon gas, and are series-connected between secondary windings of the oscillation transformer T. Diodes D1 and D2 as rectifiers provided for each of several low-pressure discharge lamps are connected between electrodes of the low- pressure discharge lamps to thereby constitute a closed circuit, and are interconnected for each closed circuit so that polarities are reversed in direction relative to the oscillation transformer T. This can equalize a bipolar high-frequency current value flowing through an output winding of the oscillation transformer T, and therefore, the consumption power can be reduced and the cost can be lowered.

Title: Precise moving table
Inventor: NEGISHI MASATO
IPC: B23Q1/25
Filed: 1988-01-29
Abstract: PURPOSE:To control movement with a high precision by providing a cooling means which cools a stage driving means as a heating body and controlling the cooling means so that the temperature difference between a base and a linear motor is zero. CONSTITUTION:When the temperature of a coil rises by the heat generated by a coil 11 of the linear motor, temperatures of a yoke 12 and a spacer 13 surrounding this coil rise, and resistance values of temperature sensors 9 and 9 attached to a temperature sensor attaching pit 14 are increased. Meanwhile, resistance values of reference temperature sensors 30 and 30 attached to the base are not changed because the rise of temperature of the base is slower than that of the yoke of the linear motor. Consequently, the balance of a temperature difference detecting bridge circuit is lost to generate an output voltage. This voltage is amplified to open a solenoid valve. Since the solenoid valve is opened, a refrigerant sent with a pressure by a pump is led to a linear motor cooling duct (refrigerant path 16) through a flexible tube 22 to remove the heat. Thus, the temperature difference between the linear motor and the base is approximated to zero by this control circuit.
